What is Voice Over IP? What is Voice Over IP (VoIP)? Voice Over IP is a general term used to describe the transmission of voice over IP-based data networks. There are several different VoIP protocols in use worldwide. The most recent protocol, and the protocol used by the XN120, is called Session Initiation Protocol (SIP). SIP is defined by the Internet Engineering Task Force (see http://www.ietf.org). SIP Trunks can be used to connect the XN120 to other XN120 systems (or some other SIP-compliant telephone systems). This allows calls to be made between the systems over existing data networks rather than using the PSTN. Note: The are many issues that need to be considered before implementing VoIP and it is highly recommended that you consult the NEC Infrontia Voice Over IP Reference Manual (991451-5) before attempting this. XN120 VOIPU Cards Available Each XN120 VOIPU card has 4 Digital Signal Processors (DSP) on board. Each DSP can handle one VoIP call. There is also an optional 4 port daughterboard that can be installed onto the VOIPU to increase the number of DSPs to 8. The photograph below shows a 4VOIPU card with the 4VOIPUDB installed. The card provides 8 DSP resources and therefore supports up to 8 simultaneous VoIP calls. Boot Run/Blk Load Reset Ethernet port Daughter- Board Debug Port Do not use Compact Flash Socket Note: An EXIFU-A1 is also required for VoIP on the XN120. Please refer to the EXIFU Guide (991423-5) for further information about this card The VOIPU cards are installed in the 2OPBOX unit, refer to the guide supplied with the 2OPBOX for installation instructions. Each 20PBOX unit can have up to two VOIPU cards installed. XN120 Voice Over IP Card Guide 3
System Connection Diagram System Connection Diagram A VOIPU card has one Ethernet port only, even if a VOIPUDB is installed. This port is used to transmit/receive the IP packets for all calls active on the card. Each VOIPU card, and the Ethernet port on the EXIFU-A1 connects to an Ethernet hub (or Switched Hub) provided by the customer.

What s Included? 1- Unpack the Card. The VOIPU card is not supplied with any connection cables. Additional Items Required: Cross head screwdriver. RJ45 patch cable for each VOIPU. (straight through connections). Optional Items You must have a spare slot available in a 2OPBOX to install each VOIPU card. 2- Install Daughterboard (if required).! Observe anti-static precautions when handling the VOIPU cards. Wear a suitable anti-static strap connected to an Earth point. Place the VOIPU on a flat surface, with the PCB facing upwards. Remove the daughterboard from its packaging and locate the black 40-pin connector on the PCB (CN11 on the VOIPU and CN6 on the Daughterboard). Gently place the daughterboard onto the VOIPU so that the 4 plastic legs locate into the holes on the VOIPU and the 40-pin connectors meet up. Apply firm, even pressure to the four plastic areas on the daughterboard until the legs click into place on the VoIPU. 3- Power Off the System. You must power off the XN120 system before you install the VOIPU card into a slot in the 2OPBOX. 4- Fit the EXIFU-A1. Refer to the installation instructions supplied with the EXIFU-A1. 5- Fit the 2OPBOX. Refer to the installation instructions supplied with the 2OPBOX. The VOIPU card is installed into a free slot in a 2OPBOX, ensure you fit the 2OPBOX before you install the VOIPU card. 6 XN120 Voice Over IP Card Guide
Install the VOIPU Card 6- Install the VOIPU Card! Observe anti-static precautions when handling the VOIPU cards. Wear a suitable anti-static strap connected to an Earth point. Installation Considerations: Each VOIPU card will use a slot in a 2OPBOX. Each 2OPBOX has two slots. The XN120 can have up to three 2OPBOXs; one box can be connected to each XN120 Unit (1 main unit plus 2 expansion units). Are there sufficient trunk ports available for the VOIPU card? The XN120 can have a maximum of 51 trunk ports, including the trunks used by the XN120 unit(s). A VOIPU will use 4 of the XN120 s trunk ports. A VOIPU with a VOIPUDB installed will use 8 of the XN120 s trunk ports. If there are not sufficient trunks ports available on the system when the VOIPU card is installed the card will not initialise. 1 Fit the VOIPU card into a slot in the 2OPBOX Ensure the power is switched OFF to the XN120 system. Loosen the two screws and remove the lid of the 2OPBOX. Fit the VOIPU card into any of the slots. (If you have just one card to install then use Slot CN1 as this will keep the ports assigned to the card in order should you later install another card into CN2). Slot CN2 Slot CN1 2 Tighten the screw at the bottom edge of the VOIPU to secure the card to the 2OPBOX mounting rail 3 Refit the 2OPBOX Lid XN120 Voice Over IP Card Guide 7
Connect the VOIPU Circuits to the Data Network 7- Connect the VOIPU Circuits to the Data Network 1 Connect each VOIPU circuit to the data network. At this point you should also connect the EXIFU-A1 Ethernet port to the data network.

Before you power on the system check that the NORMAL switch is set to ON. This will ensure that the system memory retains your configuration. The NORMAL switch is located to the right of the MOH/Page connector on the main unit, refer to the Getting Started Guide supplied with the XN120 for further information. 2 The VOIPU card(s) will be automatically configured. Check the VOIPU card(s) has automatically configured by the LIVE lamp flashing green on each card. If the LIVE lamp is off the card is not initialised correctly. Check the card is fully inserted into the slot (power off the system first). Check the slot has not had a different type of card installed, see Program 10-03-01 below. Check there are sufficient trunk ports available on the system, maximum of 51 trunks. XN120 Voice Over IP Card Guide 9
Configure IP Addresses 9- Configure the IP Addresses. All Ethernet ports need to have valid IP addresses assigned. IP Address details are usually supplied by the customer s Network Administrator. Note that the XN120 has default IP addresses assigned to each Ethernet port. If these addresses conflict with addresses used on the customers existing network, network disruption will occur. Default IP details: EXIFU-A1 IP Address 172.16.0.10 VOIPU Slot 5 172.16.0.24 (Cabinet 1, CN1) VOIPU Slot 6 172.16.0.25 (Cabinet 1, CN2) VOIPU Slot 11 172.16.0.30 (Cabinet 2, CN1) VOIPU Slot 12 172.16.0.31 (Cabinet 2, CN2) VOIPU Slot 17 172.16.0.36 (Cabinet 3, CN1) VOIPU Slot 18 172.16.0.37 (Cabinet 3, CN2) Subnet Mask 255.255.0.0 Default Gateway 0.0.0.0 This guide shows the configuration required to connect the XN120 to the customers Ethernet LAN.! You will need a fixed IP address and the appropriate Subnet Mask for the XN120, this must be specified by the Network Administrator responsible for the customers LAN. 1 Program 10-12-01 Enter the IP Address of the XN120 system. Enter the Subnet Mask. 10-12-01 172.16.0.10 Enter the IP Address, you must enter three digits for each field. Example 172 016 000 010 you do not need to enter the decimal points.

Test IP Connectivity 10- Test IP Connectivity Once the VOIP card and EXIFU-A1 Ethernet ports have been configured and connected to the Data Network you should test connectivity. Test 1 Layer 1 Lamp. Each Ethernet port has two lamps next to the RJ45 connector to indicate the status of the port.! This is a basic confirmation that the connection is made, it does not necessarily mean that the circuit is working fully. The orange link LED indicates that there is a Layer 1 link with the Ethernet hub/switch. This should be on when a connection is present. The green activity LED indicates Ethernet activity. Every frame that is transmitted or received by the Ethernet port will cause the activity LED to light temporarily. When calls are in progress, or on a busy Ethernet network you will notice that this LED is lit almost constantly. Activity LED Link LED Test 2 PING. If there is a layer 1 connection and the IP details are correct, it should be possible to ping the VOIPU card and the EXIFU-A1 Ethernet port. PING (Packet InterNet Groper) is a standard utility that is run from a PC that sends a small packet of data to a specified IP address. When the ping is received, the receiving device returns the data to the sender. The original sender can then determine if the device is available on the network and can indicate the network delay between the two endpoints. To ping from a Microsoft Windows PC (method may vary slightly dependant on Operating system): Ensure the PC has a valid IP address and is connected to the data network Click on the Start button Click on Run Type cmd in the Open dialogue box and click OK. A command prompt window will open. Type ping 172.16.0.10 (replace 172.16.0.10 with the actual IP address that you want to test) and then press Enter. 12 XN120 Voice Over IP Card Guide

This ensures that the IP routing is functioning correctly. XN120 Voice Over IP Card Guide 13
Configure SIP Trunks 11- Configure SIP Trunks Changing the VOIPU trunks to SIP mode It is necessary to change each VOIPU trunk to SIP mode by Program 10-03-01. Note. When you enter Program 10-03-01 you will see the setting for Port 01 of Slot 01 which is always a Hybrid extension port. So before you make any changes you must use the VOLUME keys to scroll to the correct slot number that your VOIPU card is plugged into, see below. The 2OPBOX connected to the Main XN120 unit is assigned slots 5 and 6. The 2OPBOX connected to the First XN120 expansion unit is assigned slots 11 and 12. The 2OPBOX connected to the Second XN120 expansion unit is assigned slots 17 and 18. Setting Global SIP Parameters The XN120 has several system-wide settings that have to be programmed to enable SIP to work. These items are located in Program 10-28. Setting CODEC Options The XN120 uses a CODEC (Coder/Decoder) to convert speech into IP packets. Industry standard CODECs are used to allow interoperability between un-like devices. The choice of CODEC to use will depend on various factors, including the type of data network, the amount of bandwidth available and the capabilities of connected equipment. The XN120 CODEC (called the Audio Capability Priority ) is changed in PRG84-13-28 for SIP Trunk calls. Note: The are many issues that need to be considered before implementing VoIP and it is highly recommended that you consult the NEC Infrontia Voice Over IP Reference Manual (991451-5) before attempting this. The example configuration on Page 31 gives an example of the configuration required on a typical SIP Network installation. 14 XN120 Voice Over IP Card Guide

Configure Incoming Calls 12- Configure Incoming Calls The XN120 supports two methods of handling incoming SIP calls; normal (non-ddi) or DDI. This guide explains the general operation only, for an explanation of every option refer to the XN120 Features Manual 991434-5. Non-DDI Operation. If the SIP network does not supply any DDI digits then the BRI lines can be routed in exactly the same way that you would route an analogue trunk. Refer to the XN120 Getting Started Guide for more detail. In brief, Route each VOIPU line to an Incoming Ring Group (IRG) in program 22-05-01. A line can route to a different IRG in each night mode. You then place telephones into IRG s in program 22-04-01, a phone can be a member of more than one IRG. Route each VOIPU line to a Ring Group. You can have a different Ring Group per night mode. Program 22-05-01 Assign telephones to the Ring Group. Program 22-04-01 XN120 Voice Over IP Card Guide 17

Configure Incoming Calls DDI Operation. The XN120 will can also route DDI numbers. This allows calls to be presented to individual extensions (deskto-desk dialing). This is the most common method of handling incoming SIP calls. With DDI operation the network will pass the last digits of the dialed number to the XN120. The XN120 then compares these digits to a look up table, if the number matches any entry in the look up table it will follow the routing specified. In brief, Set each VOIPU line as DDI mode in Program 22-02-01, ensure you do this for all night modes. You then place the lines into Trunk Groups in Program 14-05-01, route each Trunk Group to an area within the DDI table in Program 22-13-01. Then enter all DDI numbers in the area specified with their associated destination in Program 22-11-01. Set each VOIPU line as DDI mode. Program 22-02-01 Assign each VOIPU line to a Trunk Group. Program 14-05-01 Point the Trunk Group to an area of the DDI table. You can assign a different area per night mode. Program 22-13-01 Enter the DDI numbers and destinations in the DDI table. Program 22-11-01 See below for a detailed description of each step. XN120 Voice Over IP Card Guide 19

You can enter any quantity of digits up to a maximum of 8. You do not need to enter the full quantity of received digits, for example, if the network is sending four DDI digits in the range from 3100 to 3199 you can just enter receive DDI digits of 00 to 99 in the XN120 and it will match them correctly. Target number. You can enter any quantity of digits up to a maximum of 36. The target number can be any telephone extension number (e.g. 203) and the DDI will route to the telephone. The target can be any department group pilot number (e.g. 502) and the DDI will route to the department group. The target can be a trunk access code followed by an outside number, refer to the XN120 Features Manual 991434-5 for further details. Name. You can enter any alpha-numeric name up to a maximum of 12 characters, try to keep the name below 8 characters otherwise it will be truncated. You can enter the name related to the DDI, this will help identify the incoming DDI calls by showing its name on the LCD display of the XN120 system phones. Transfer Operation Mode. You can specify the operation when the target number is busy or ring no answer. If the target number is busy you can either return busy tone to the incoming caller or overflow to an alternative target. If the target is ring no answer you can either continue to ring indefinitely or overflow to an alternative target. Transfer Target 1. This is the first overflow target if you have specified overflow in the Transfer Operation Mode.

Configure Outgoing Calls 13- Configure Outgoing Calls There are several methods of dialing SIP destinations using the XN120. All of these methods (detailed below) use a standard dialing table to determine the IP address of the remote destination. It should be noted that SIP calls can only be made using en-bloc dialing. This means that there will be a delay after dialing the digits before the call is set up. This delay is called the inter-digit timer and is configured in PRG21-01-03. This timer can be reduced but it is a system-wide setting so this will impact on other trunks in the system. An alternative is to dial a # after the required digits. # indicates the end of the dialled digits and this causes the call to be set up immediately. Manually seize a VOIPU trunk (line key) The exchange lines of each VOIPU circuit can be presented under a function key in the same way as the analogue/bri lines. The lines provided by each VOIPU card can be confirmed by Program 10-03-01, explained previously. See the XN120 Getting Started Guide for details of programming Function Keys. Automatically seize a VOIPU trunk (dial 9) To place an outgoing call the user can dial 9 to seize any free line. At default dialing 9 will seize any free trunk in Trunk Group number 1. If you have changed the Trunk Group number of the VOIPU lines (in Program 14-05-01) you will also need to include the new trunk group number within the route used when 9 is dialed. You can assign up to 4 trunk group numbers per route by Program 14-06-01. Assign the Route used by each telephone when 9 is dialed. You can assign a different route per night mode Program 21-02-01 Assign the Trunk Group(s) used for each route. Up to 4 trunk groups can be included per route. Program 14-06-01 Assign the trunks to each trunk group. Program 14-05-01 This method is usually used when all calls are to be made via the VOIPU circuits. Flexible Routing (f-route) Many XN120 installations utilise SIP trunks for site-to-site calls and the PSTN for calls to external numbers. Typically 9 is used as the first digit for calls to PSTN numbers and internal calls have a different numbering scheme. To allow calls to be routed the relevant trunk automatically, F-route can be used. F-Route configuration is outside the scope of this document. Please refer to the XN120 Programming Reference Manual (991435-5) for further information. System Interconnection Table When calls are made via Analogue or BRI trunks, the network provider routes the call to the required destination. The XN120 just has to send the digits to the provider and their network is configured with the routing information to set up the call. This is essential as there are millions of possible telephone numbers that you could dial. 26 XN120 Voice Over IP Card Guide
Configure Outgoing Calls When SIP trunks are used, typically there are no more than a hundred remote destinations. As the destinations are usually all located within a private data network there needs to be a method of translating dialed numbers to IP addresses these cannot be automatically determined as in the previous example. The XN120 has a dialing table that is referred to whenever a call is attempted via a VOIPU trunk. The dialing table allows up to 1000 telephone number/ip address entries. The flowchart below shows how the routing decisions are made in a typical XN120 installation. XN120 Voice Over IP Card Guide 27
Configure Outgoing Calls To configure the XN120 routing table: Program 10-23-01 There are 1000 DDI entries. One entry is required for each remote destination. System Interconnection. This switches on or off the specified table entry. The IP address is the address of the remote destination. If this is another XN120 system, this IP address should be the one assigned to its EXIFU-A1 Ethernet port. The Call Control Port cannot be changed. The dialed digits should be sufficient to correctly identify the remote site. For example, if you have several XN120 systems with numbering plans: 012xxx (London) 011xxx (Rome) 023xxx (Dublin) you would need to specify at least three digits, otherwise the XN120 would not know which destination to send calls beginning with 01 to. 10-03-01 No.1 SysInterconnect0 Select the correct table entry number 1-1000 with the Vol. keys. Press 1 to enable this table entry Press HOLD to confirm the entry and step to the next option. 10-03-02 No.1 0. 0. 0. 0 Enter the IP Address, you must enter three digits for each field. Example 172 016 000 010 you do not need to enter the decimal points. Press HOLD to confirm the entry and step to the next option. 10-03-03 No.1 CallCTRPort 1720 Press Vol to select the entry number Press HOLD to step to the next option (it is not possible to change this item) 10-03-03 No.1 Dial Enter the dialed digits. This should be enough digits to identify the destination. Press HOLD to confirm the entry and step to the next table entry. Repeat the above steps until all required entries are complete. Press DC several times when you are done to return to the Program Mode. (Press SPK to save changes and exit if you are finished). 28 XN120 Voice Over IP Card Guide

Configure Outgoing Calls 14- Configure Caller ID Receiving Caller ID The VOIPU lines will receiver Caller ID at default, the Caller ID will be displayed at the LCD display of the XN120 telephones or normal telephones with caller ID enabled (Caller ID is enabled by Program 15-03-09 for each normal telephone). For the correct display of the CLIP you must enable the automatic insertion of the prefix digits (0 for national calls and 00 for international calls). This is enabled by Program 20-19-03, set this option to 1 to enable the insertion of the 0 or 00 prefix digits. If the Caller ID received on an incoming call matches an entry in the system Telephone Book then the name assigned in the Telephone Book will also be displayed. Sending Caller ID The system can send caller ID for outgoing calls. The Caller ID can be specified per VOIPU line (PRG21-17), per telephone (PRG21-19) and per system (PRG10-28-04). The flowchart below shows which Caller ID setting will be used for a SIP call. 30 XN120 Voice Over IP Card Guide
